Theres also some healthy large sabal palms in knightdale that have been there since 2007. Those are pretty tall. I agree with you @Thor we are about as cold as they can handle without having to protect them every year. The hardiness maps have Raleigh as zone 7b with a mean min of 9 but they quote the 1976-2005 por which at this point is not only outdated but a bit colder than other pors. Id say 8A is probably truer now , even borderline 8B in the UHI of ITB of 440.
